STAPLE AND NAIL FULLER.

Specification of Letters Patent. Pate ted Oct. 12, 1920.

Application filed December 29, 1919. Serial No. 347,939.

7 '0 all whom it may concern:

Be it known that I, CHARLES SGHROEDER, a citizen of the United States,and resident of Neillsville, in the county of Clark and State ofWisconsin, have invented certain new and useful Improvements in Stapleand Nail Pullers; and I do hereby declare that the following is a full,clear, and exact descri tion thereof.

3/ y invention relates to new and useful improvements in devices forpulling nails and staples, or for lifting band iron strips from packingboxes or lids thereof, and for otherwise exerting a prying leverageaction, and more particularly of that type comprising a work engagingmember adapted to be driven into operative position to an article to bepried and pivotally connected with a suitable fulcrum base whereby toafford a firm support for the tool in operation thereof.

It is in general the object of my invention to simplify and otherwiseimprove the structure and to increase the efiiciency of devices of thischaracter and it is more particularly my object to provide a devicewherein a direct driving action may be provided for the work engagingportion thereof, so as to facilitate its engagement under a nail head orthe shank portion of a staple to be pulled.

A specific object in this latter connection resides in the provision ofa fulcrum base member in pivotal connection with the main lever portionof the device and which is adapted to extend in longitudinal alinementwith the work engaging toe portion of the lever member to facilitatedriving said member under an article to be pried.

With the above and other objects and advantages in view, which will beapparent as the description proceeds, my invention resides in the novelfeatures of construction, combination and arrangement of the parts ashereinafter described and defined by the appended claim.

In the accompanying drawings:

Figure 1 is a side elevational view of a nail and staple pullerembodying my invention, an extension handle member being shown insection upon the shank of the lever member of the device.

Fig. 2 is a bottom view of the device.

Fig. 3 is a transverse sectional view on a plane indicated by the line33 of Fig. 1.

Referring now more particularly to the accompanying drawings, which showmy invention embodied in a nail and staple puller, there is provided amain lever member having its intermediate portions enlarged and havingits endfportions disposed at an obtuse angle to each other and shaped toform a handle shank 5 and a work engaging toe 6 respectively, said workengaging toe being flattened to provide a decidedly oblong cross sectionand having a V-shaped recess 7 in its end adapted to receive the shankof a nail or other member to be pulled, the flattened shape of the workengaging toe facilitating its insertion under a member to be pried, suchas the bight portion of a staple or the like, whereby the staple willnot slip off of the toe as the prying action is instituted. The heelportion of the lever member is cut away at its sides to define a pivotlug 8 and a pair of seating shoulders 9 at the side of the pivot lug.The shoulder 9 extends concentrically with the pivot point of the lug 8and toward the level thereof. This concentric portion of the shoulder isintersected by a downwardly and forwardly extended radial face 13, whichface in turn is intersected by a short concentric shoulder portion 13,the same merging into the fiat sole face of the lifting lever. Thus apair of V- shaped pockets are formed for the forwardly extendedcorrespondingly shaped fingers 11, which fingers together with heelportions 10 thereof correspond in outline to the shoulders just defined,the said fingers being integral parts of a fulcrum base anddriving'block 11. The bifurcated cars 10 are pivotally connected to thepivot lug 8 by a bolt 12, which bolt, best shown in Fig. 3 of thedrawings, is of slightly less diameter than the bolt aperture of the lug8, whereby strain upon said bolt is eliminated.

I have thus provided an exceedingly simple and effective device whichmay be driven into prying or pulling relation to a nail or staple byblows imparted to the rear end of the fulcrum base member, thusfacilitating the convenient application of the device, and the pullingor prying operation may then be carried out by simply depressing thelever shank 5. If desired an extension handle section 14 may be fittedon this shank for the purpose of procuring a greater leverage.

While I have shown and described my improved device as beingparticularly adapted for use as a nail or staple puller, it will beappr'eciatedthat the device may be applied to pinch bar or similar uses,in which instance the toe portions of thedevice may be made blunter, andvarious other changes and modifications of structure may be made to meetdiffering conditions of use and manufacture, Without departing in anymanner from the spirit of my invention. What is claimed is: e 1

A device of the class described comprising a 10 lever member, having aheel portion which is cut away to form a pivot lug having concentricallydisposed shoulders that extend toward the toe portionof the lever, theconcentric shoulders being intersected by down- 15 Wardly and forwardlyextended radial faces the same being interrupted by a second set ofconcentric portions, whereby V-shaped recesses are formed, a drivingblock in pivotal union with the heel of the lever, the driving blockbeing provided With forwardly extended fingers Which correspond inoutline to the shoulders formed in the heel portion of the lever, tooppose driving strain of said block, and a loose pivot connectionbetween the fingers of the block and lever.

In testimony that I claim the foregoing I have hereunto set my hand atNeillsville, in the county of Clark and State of Wisconsin.
